Abstract (en)
A prepreg consisting of a fiber reinforcement material and a resin composition containing a bismaleimide resin is molded through a first heating step in which the prepreg is held at a temperature (T<sub>1</sub>) equal to or higher than a temperature at which the resin composition exhibits a viscosity of 100 [Pa·s] and equal to or lower than a temperature at which the resin composition exhibits the minimum viscosity for 30 minutes or more, followed by being held at a temperature equal to or higher than a curing temperature of the bismaleimide resin.
